ABB / General Electric THHQL32025 Miniature Circuit Breaker

This breaker is designed for use in GE AQ Lighting Panels and GE PowerMark Gold Load Centers that accept Q-Line plug-in circuit breakers.

Both are 1-inch wide per pole Q-Line plug-in breakers, but they have different interrupting capacities. THQL breakers are rated for 10kAIC, while THHQL breakers like the THHQL32025 feature a higher 22kAIC rating.

As a standard 3-pole Q-Line breaker, it requires three 1-inch spaces (3 inches total) in a compatible GE load center or lighting panel.

Yes, the THHQL32025 has the same physical dimensions and mounting style as the THQL32025. It can be used as a direct replacement and provides an upgraded 22kAIC interrupting capacity.

No, this is a plug-in circuit breaker. For GE panels requiring bolt-on connections, you would need a THQB or THHQB series breaker instead.

The LI code indicates that the thermal-magnetic trip unit provides Long-Time (thermal) overload protection and Instantaneous (magnetic) short-circuit protection.

No. THQP breakers are half-inch wide space-saving breakers. The THHQL32025 is a full-size 1-inch per pole breaker and will only fit in slots designed for standard Q-Line breakers.

The interrupting capacity (AIC) must meet or exceed the available fault current at the panel. Using a 22kAIC breaker ensures it can safely clear higher fault currents than a standard 10kAIC breaker without sustaining damage.

No. This breaker is specifically listed for GE and ABB panels. You should only install it in load centers where GE Q-Line breakers are explicitly approved on the panel label.
